SEEDING ATTACHMENT FOR GANG-FLOWS.

SPECIFICATION forming part of Letters Patent No. 646,004, dated March 27, 1900.

Applitationflledfebruary 9,1898. sriaimeeenov. (No model.) V

To all? whom it may concerns 5 Be it knownthat I, ALBERT J. MALSEARY, a citizen of the United States, residing at Stockton,- county of San Joaquin, and State of Cali fornia, have invented certain new and useful Improvements in Seeding Attachments for Gang Plows; and I hereby declare the followiug to be'a full, clear, and exact description of the same, reference being had to the acco m panying drawings,-forming a part of this specification.

--One of the objects of'my invention is to provide a seeding attachment for gang-plows .or the like" in which the seed-furrows shall be opened'with as little friction and expenditure of power as possible, onc'i'n'which the furrowclosing devices maybe maintainedalways in exact alinement in rear of the furrow-opening devices and seedrconductors, and One in which the seedboxmaybe supported altogether on the furrow openers and closers,

thereby saving the weight andextra draft of- I the usual independentbearing-wheels,

A further object ofmy invention is to provide anattachment for'gang-plows so constructed that the furrow-opening disks shall revolve, always in the same generaldirection or plane, as in the direction of the draft of the device'as a whole, thus reducing friction in turning corners, and 'oneso'constructed as to permit a limited lateral freedom of movement of the seed-planting devices, so astoallow the machine to pass readilyvamong the .loose rocks uponIt-he land; p I My inventionfurthermore resides in the of a pair-of the caster-arms, showing'the'position of the wheels E and C, the boot H, the headpiece F, also the scrapers I and J, one of the outer pair of the caster-arms being shown with the wheel 0 flanged, as at G, and the brace V on only one side instead of both sides, 1

as shown in the interior casters in Figs..I and II. Fig. V is a perspectiveview of the end of the plow-beam, showing the manner of securing the fiexiblesupport W of the drill to the plow-beam. Fig. VI is a diagram of the swiveling frame to which are fiexibly attached the caster-arms, the seedbox-braces, &c., the

dotted lines showing how it may. swing or swivel in turning either to the right or left.

- Referring to the drawings, A represents a gang-plow having a .triangularframe with plows attached thereto, the style being locallyknown 'as the Stockton? gang-plow. The seedbox A is-mounted pivotally on two arms B B near their, rear ends, as shown in Figs. I andII."

OO 0 Care a series of disksor wheelsserv-i 76 ing the double purpose of supporting the weight of the machine and of forming the drills into which theseed is to be dropped- DD D D are pairs of caster-arms forming the frames in which each of the severalwheels 7 5 O O G O and E E'E E are journaled; and ro-' tate-independently and having at the front: end of said caster-arms headpieces F F'F F or other devices, to which the said caster arms Y are rigidly secured. The drill-forming wheels 86 should bemade with a V-sha'ped periphery, or .for some conditions of soil preferably concave disks should be used. 5 The hubs should i g I be large enough to admit of wooden bearings or antifriction-roller bearings suitablypro tected from dust and grit by sand-caps. The projecting rim G. is to be'oast-with' the drillformingwheels O O 050, orit may be sepa-' rate and secured with bolts.

The object of the'projecting rim G is-to 96 form a stop for preventing the Wheels from sinking too deeply into the ground, thus forming drills of a uniform depth.

.As the caster-frame arms D D D D extend rearwardly they continue in a slightly-down-' ward slant and serve as'a support for the boot H and the wheels 0 O O O andE EEE. One arm of each set of beams D D extends back far enough to admit of a securing place for a scraper I, which may be used in sticky 10o soils for the wheels E E E E. Provision is also made for a scraper on each side of the drill-forming wheels 0 C G O, as shown on one of the sets on the under side, (marked J,)

as in Fig. IV. To the righthand outside wheel of the series is secured a flanged or sprocket wheel K, suitable for carrying a small cable chain, over which and a like wheel L a matched endless chain 0 rotates and drives the seed mechanism in the seedbox.

P is a spring for maintaining a uniform tension of the said chain, the said chain passing over the two flanged wheels M and N, which are journaled upon two shafts secured to the spring P,as will be explained farther on.

To the horizontal cross-bar Q boxes RR R R are secured at a uniform distance apart, corresponding in number to the drill-formin g wheels, which may be any number desired. In these boxings the stems or spindles of the headpieces F F F F of each independent caster-frame arejournaled, being held in position by means of an ordinary cotter-pin X. Two of the boxes R R R B have extra lugs S S, cast to admit of a hitching-place for the tongue T, in such a manner that the tongue can be altered quickly from a loose to a stiff tongue, and vice versa, by using one or two points of support, as shown in Fig. I. The stems of the headpieces F F of the two outside casters should be longer than the other stems, so that the arms B B may be keyed rigidly thereto.

Referring to the arms B B, they form the main support of the seedbox A at points '0 o, where the box is pivotallyattached to said arms at each of its ends. These arms should extend over the center of each of the outside wheels 0 O and be connected by the bar U, which holds in place the braces V V V V, which bar also pivots correspondingly with the seedbox and aids in supporting it.

The object of the swiveling construction is to avoid undue strain in turning corners. The pivotal devices of the seedbox, in connection with the arms B B, are rigidly secured to the two outside spindles of the headpieces F F and are pivotally attached to the bar U and bracesV V V V, so that the casters D' D D D work in unison with the rest of the machine without undue strain upon the parts. It will be observed that in turning corners the swiveling construction will force the said flanged chain-wheels K L M N out of line; but it will also be observed that the spring P, to which the wheels M N are attached, will maintain the tension of the chain and keep it in place on the wheels L K.

The seeding mechanism in the seedbox is of the usual construetionthat is, by means of the operative connection with the wheels K L it discharges the seed intermittently at regular intervals through holes in the bottom of the box. The seed passing outof the seedbox drops through the tubes Z Z Z Z in the ordinary way, said tubes being guided or held in place by the boots H, which lead the grain into the grooves or drills made by the wheels or disks 0 C G O. The wheels E E E E follow and cover the seed.

Z is a staple where the tongue T is to be hooked or otherwise fastened to a plow or .tors position.

cultivator cross-bar to draw the drill, and Z the point where the adjustable arm W is to be flexibly attached to the plow, the otherend of the arm WV being also flexibly attached to the left-hand end of the bar Q. By this arm W, which is adjustable, the drill is kept at the proper place in rear of the plow, and by means of the two loose joints, one being at each end of the arm, the drill is allowed to rise or fall according to the shape of the ground, regardless of the plows or cultiva- To prevent the swiveling action of the machine, (if desirable at any time,) the brace Z should be hooked into the eye Z.

I am aware that prior to my invention graindrill seeding attachments for gang-plows or grain-drills have been used with seedboxes and with rotating wheels having upon their periphery arrow-head-shaped ribs and alternatin g arrow-headshaped depressions as feeders, also sliding adjustable valves to regulate the feed and tubes and boots to conduct the seed to the ground or drills. I therefore do not claim such a combination broadly, and do not claim the rotating wheels or other mechanism in the seedbox at all.

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. In a seeding attachment for gang plows or cultivators the pivoted bars B B and crossbar U carrying the seedbox A in combination with the pivoted head-pieces F, carrying the furrow-openers, seed-conductors and furrow-closing devices, all substantially as described.

2. In a seeding attachment for gang plows or cultivators, the combination of a frame having longitudinal parallel pivoted bars, B, B, connected pivotally by a cross-bar U, a

seedbox A mounted on the longitudinal bars 7 B, B, a series of furrow-openers pivotally connected to the cross-bar U, and seed-conductors loosely interposed between the seedbox and the furrow-openers substantially as described.

3. In a seeding attachment for gang plows, or cultivators, the combination of a frame, a seedbox mounted upon pivots upon said frame for permitting the entire seeding de-. vice to swing around in turning corners, a

tance laterally from the plow, said bar having at one end a flexible connection with the left-hand timber of the plow, near its rear end, and the other end of said bar has a flexible connection with the seeding device, near the left-hand end of the bar Q, substantially as described.

5. In a draft mechanism foraseeding device,

the combination of lugs S, a double tongue T, pivoted to swing vertically on said lugs, and means for securing said tongue rigidly in said lugs when desired, substantially as described. I

6. In a seeding device the combination of a frame pivoted to swing laterally, having a series of laterally-swinging caster-arms D, pivoted at their front ends to bar Q of said frame, a furrow-opener and a seed-conductor mounted on each pivotally-swung pair of castor-arms, supports extending upwardly from each pair of arms, on which supports the bar U of the frame is pivotally mounted, and a seedbox carried on the frame substantially as described.

7. In a seeding device a series of laterallyswinging caster-arms pivoted at their forward ends to the bar Q of the frame, said casterarms carrying furrow-openers, seed-conductors and to rrowclosers, laterall y-turnin g pivots connecting the frame with its braces and supports, and pivots connecting the seedbox with the frame, the brace for connecting the pivoting-arms and frame rigidly when desired, the sheave or wheel upon the furrowopener, over which runs the chain for driving the sheave or wheel located upon the outer end of the shaft extending through the seedbox, for driving any suitable seed-discharging mechanism within the seedbox, substantially as described.

8. In a draft mechanism for a seeding device, the combination of lugs S, a double tongue T pivoted to swing vertically on said lugs, and means for securing said tongue rigidly to said lugs when desired, substantially as described.
